Round 3: Problem 1

with 3 comments

Two CUNY students (over the age of 21) are having an all-day study party. One student brings 3 bottles of beer and another brings 5 bottles of beer. A third student joins them later and they all enjoy the beer. When the “studying” ends, the one who came late, wanting to contribute his fair share of the total cost of the party, leaves $8. How should the $8 be divided up fairly amongst the two students who brought the beer?

Submissions for round 3 are due by Sunday, April 12 at 11:59 p.m. Solution will be posted (if we solve it) immediately after submissions are over.

    • How ’bout that… Thought you were making a joke. Apparently they changed it. It originally read like I have it (we directly copy and paste the questions).

  2. After the completion of this round, I told my friend of this problem and he said, “were they all girls at this study-party?–only 8 beers?? come on!” and what kind of a study-party involves alcohol? ^^;;
